It imported the bookmarks from Firefox just fine. But the categorization of the bookmarks is, sorry to be critical, but buggy. Examples I can say are,
1) Techmeme, Engadget, Techcrunch etc. pages not in Sci/Tech. 2) Cricinfo, ESPN, ManUtd pages not in Sports. 3) A page on Microsoft and Cleartype was placed in Entertainment!! 4) MSBuild tutorial on Health!
and so on. You need to fix this real quick I believe. As it's one of your main selling point.
1) The Search lens image can be clickable. I atleast expected it to be.Only way is to press Enter key. 2) If the search result don't return any results, don't change the categories left panel from general to search specific.
Overall I like it and may use it.
Besides, are you associated with AdventNet/Zoho? Just wanted to check as you have put a footnote for Vembu Technologies. Are they both related even? I might be mistaken.
